Quick Answer: Did Rolex make rectangular watches?
Yes. Rolex produced several rectangular watch models throughout the 20th century, most notably under the Cellini name. The Cellini Prince is the most significant - a rectangular-cased dress watch with a transparent caseback that allows the movement to be seen. The King Midas is another notable rectangular Rolex, produced in the 1960s and 1970s in solid gold. These models represent Rolex's acknowledgment that the rectangular case belongs at the highest level of watchmaking.
Rolex is synonymous with round watches. The Submariner, the Daytona, the Datejust - these are the references that define the brand's public image. But Rolex has always understood that the rectangular case occupies a distinct and important position in horology. The Cellini collection is where that understanding is expressed most fully, and the rectangular models within it are among the most underappreciated watches the brand has ever produced.
This guide covers the rectangular Rolex watches worth knowing: their history, design, movements, and where they sit in the broader context of rectangular watchmaking.
Why Rolex Made Rectangular Watches
Rolex built its reputation on round tool watches - watches designed for specific professional purposes, engineered to perform under pressure, and shaped accordingly. The round case is ideal for that mission. It is structurally strong, mechanically straightforward, and universally legible.
But the dress watch context demands something different. In formal and social contexts, the watch is an accessory as much as an instrument. And in that context, the rectangular case has held the dominant position since Louis Cartier drew the Tank in 1917. Rolex, aware of this, developed rectangular models specifically for buyers who wanted Rolex quality and provenance in a dress watch format.
The result was the Cellini collection - named after Renaissance artist Benvenuto Cellini - which housed Rolex's dress watch output, including its most significant rectangular references.
The Rolex Cellini Prince
The Cellini Prince is the rectangular Rolex that collectors and enthusiasts know best. Its defining feature is the transparent caseback - unusual for Rolex, which has historically kept its movements private - that allows the wearer to see the movement working. In a rectangular case, that view is framed architecturally rather than simply displayed, which makes the experience of wearing the Prince different from wearing a round watch with a similar feature.
The Prince's rectangular case is a significant departure from Rolex's standard output. The proportions are slim and elongated, the finishing is precise, and the overall impression is of a watch made for a completely different context than the Submariner or GMT-Master. This is Rolex making the argument for the rectangular case on its own terms rather than adapting a round design.
The Cellini Prince has been produced in 18ct white gold and Everose gold, reflecting its position as an uncompromising luxury object rather than an accessible entry point. It is a collector's watch - sought after specifically because it represents the lesser-known dimension of a brand most people associate exclusively with round cases.
The Rolex King Midas
Before the Cellini Prince, there was the King Midas. Produced from the 1960s through the 1970s, the King Midas was a bold rectangular watch in solid gold - case, bracelet, and all. It was designed by Gerald Genta, the same designer responsible for the Audemars Piguet Royal Oak and the Patek Philippe Nautilus, which gives it a design pedigree that extends well beyond its Rolex connection.
The King Midas was not a subtle watch. It was a statement of wealth and taste made in the most direct terms available: an entirely gold rectangular timepiece on a gold integrated bracelet. For the period, it represented exactly what the luxury watch market was producing for its wealthiest clients.
Vintage King Midas examples in good condition are now genuine collector pieces, sought after both for their Rolex provenance and their Genta design heritage.
The Rolex Cellini 4320
The Cellini 4320 is an earlier Cellini reference that established the design language the collection would develop through subsequent decades. Introduced in the 1930s, it combined a classical rectangular case with clean dial execution and Rolex's standard commitment to movement quality.
The 4320 is less visually dramatic than the Prince or the King Midas, but it represents the foundation of Rolex's rectangular dress watch output. Its proportions are restrained, its finishing is careful, and its movement - a high-precision mechanical calibre - delivers the accuracy that Rolex's reputation was built on. For collectors interested in the history of rectangular Rolex production, the 4320 is the logical starting point.
The Rolex Cellini 4651
The Cellini 4651 developed the rectangular Cellini format further, adding rounded edges to the rectangular case that created a softer, more contemporary profile than the sharper 4320. The result is a watch that occupies the space between the strict geometric precision of the Tank tradition and the more fluid design language that defined much of 1970s and 1980s luxury watchmaking.
The 4651 features a sapphire crystal that protects the dial while maintaining clarity, precise hour markers and hands on a clean dial, and the movement quality that defines the Cellini collection throughout its history. It is a more wearable proposition than the King Midas and a more contemporary one than the 4320.
Rectangular Rolex Watches in the Context of the Category
The rectangular Rolex models exist within a broader tradition of rectangular dress watches that includes the Cartier Tank (1917), the Jaeger-LeCoultre Reverso (1931), and the TAG Heuer Monaco (1969). Each of these watches makes the argument for the rectangular case from a different direction.
The Rolex contribution is specific: these are watches that carry the Rolex name - with all the quality assurance and resale value that entails - in a format that Rolex's core round catalogue does not occupy. For buyers who want Rolex provenance in a dress watch context, the rectangular Cellini models are the answer.

The King Midas is also highly collectible, particularly for buyers interested in Gerald Genta's design work and the all-gold integrated bracelet construction.
How does the Rolex Cellini Prince compare to the Cartier Tank?
Both are rectangular dress watches at the luxury end of the market. The Tank has a longer and more culturally significant history, broader name recognition, and is currently in active production. The Cellini Prince offers Rolex movement quality and the distinctive transparent caseback feature. For buyers choosing between the two, the Tank has stronger brand heritage in the rectangular format while the Prince carries Rolex's broader quality reputation.
Are rectangular Rolex watches a good investment?
Vintage rectangular Rolex models in good condition - particularly the King Midas and early Cellini references - have appreciated steadily as collector interest in non-round Rolex references has grown.
